How Do I Erase Locked Hidden Files On SanDisk 8G Flash Drive

A very tricky one and not that sure...

Can I have a model, make or anything a bit further to help.

I had a similar model from a trade show and I found that the application that does the locking was very unsecure, I resource edited it and basically remove the error box, so upon entering the program, I just pressed enter and it unlocked.

However, on a friend's one, the section was write protected and we were unable to do the same method

There many thousand of manufacturers and devices, without knowing a lot more, there is not a answer that fits all.

It would be interesting to see that dll file and see how it "unlocks" the drive.

This virus has been going around quite a bit recently and I have fixed it at least 10 times myself in the past couple of weeks.

Whilst the removers try to do a good job at removing the rootkit, they do not undo the actual damage caused by it. (Also, I have seen a few varieties that remain and can redirect Google search results, you may want to warn your friend).

I am not sure of a good/quick/easy way from a Mac, but, the easiest thing you can do from a Windows machine is to go to a command prompt (do not think you need elevated, but if you get an error, do it), and type the following:

x:
cd\
attrib -h /S

Replace x: with the letter assigned to the drive. This will go through all files on the drive and remove the hidden attribute. Unfortunately, if you have manually set it on any, this will be wiped - but not a lot of people do this on their own files.

Hope this helps, if you need any follow up help, especially as this isn't that easy, please write a comment and I (or someone else) will try to help you.
